At a whisker under £25 the Buffo isn't the most expensive U lock out there and in this case it's very much a case of you get what you pay for: resistance to attack is decent rather than exceptional and it's an acceptable deterrent for your town hack, but I can't help thinking you'd be better off throwing an extra few quid at your bike's security.

The lock itself is a fairly standard shackle and lock body fashioned from hardened steel. You get a decent frame mounting bracket and three keys. Abus rate the entry-level Buffo as a 6 on their scale that goes all the way up to 15, so we weren't expecting miracles but the lock put up a decent fight. We started off with the persuader which did a good job of mangling the shackle without actually pulling it loose. Then we went to work on the lock mechanism which didn't break either but was pretty easy to render inoperable, as it isn't well protected. That has the potential of leaving you with a locked bike and no way of unlocking it, which would be a pain.

The bolt croppers came out next, and in the end it was them that breached the defences after just over four minutes of fun. Had we started with them it would have been just half that. Enough of a fight to make it a worthwhile deterrent but the next level of locks above this (units like the Onguard Pitbull and the Master Lock Street Fortum) are significantly stronger – strong enough to resist most non-powered tools – and only about a tenner more, less if you shop around. Isn't your bike worth that?

Verdict

Not a bad lock but an extra tenner buys you something really secure

Here's how we roll at road.cc: every product is thoroughly tested for as long as it takes to get a real insight into whether it works or not. Our reviewers are experienced cyclists that we trust to be objective, and we strive to ensure that all opinions expressed are backed up by facts, but reviews are always a reviewer's informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores. It reflects both a product's function and value. Good scores are more common than bad, because fortunately good products are more common than bad. Here's what they mean:
